. GATE-OPERATING IVIECHANISM.

To all cli/tom t may concern.'

Be it known that I, FRANK Dvorak, a citizen of the United States, residing at Dickinson, in the county of Stark and State of North Dakota, have invented certain new and useful Improvements in Gate-0perating Mechanism, of which the following is a specification.

This invention relates to improvements in gate operating mechanism and as its primaryobject aims to provide a novel device of this nature which, in addition, to opening and'closingthe gate will cause a simullatching thereof.'

Another object of the invention is to provide improif'ed means that may be so actuated as to cause the positive opening or closmg movement of thegate, and means simultaneous therewith to release or retain the latch bar of the gate such as the case may be, thereby making the entire operation simultaneous and obviating Vthe delay in unlatching the gate and opening the same at different times. f Y A further object is to provide improved latch means which may be quickly actuated so as to release or retain the latch Ybar of the gate in an effectual manner, the said latch means being of a durable construction and so iformed that it may be manufactured very cheaply.

A still further object of the invention is to provide a device of the type in question7 that is as a whole, extremely simple in construction and which, it is believed, may be manufactured at a minimum cost.

Various other objects and advantages will become apparent during the continuanceof' the following description.

The above and other objects which will become apparent, are accomplished by such means as are shown in their preferred form in the accompanying drawings, described in the following specification and then more specifically pointed out in the appended claim.

In the accompanying drawings wherein like characters designate like parts throughout the several views; Figure 1 is a diagrammatic view of my invention as shown in its preferred embodiment. Fig. 2 is a sectional view taken on line 2-2 of Fig. 1. Fig. 3 is a view in detail showing the specilic form of latch means.

In the drawings the numerals 10 and 11 designate a pair of upstanding supporting Specication of Letters Patent. Application mee september 14, 1915.

posts that are spaced apart a suitable distance and may be anchored to the .gro1iind, such as by embedding the ends thereof in concrete or the like. A cross-piece 12 con nectsthe upper ends of the posts 10 and 11 and is suitably braced by guy rods 13 so as to obviate lateral displacement thereof. Any suitable means may be employed to retain the lower ends of the guy rods. However in the drawings I have shown the same connection with a pair of posts 14.- which project slightly above the surface of the ground.

rlhe gate which is designated in its entirety by the numeral 15 consists of a pair of vertical end pieces 16 and 17 which are connected by a plurality of longitudinal slats 18 and a diagonally extending brace member 19. A shaft 20 extends longitudina-lly through the end piece 16 of the gate, its lower end 21 projecting slightly below the lower end thereof' and being journaled in a bracket 22 in order to provide a bearing for the gate.` The upper end of the rod 20 is in turn passed through a suitable aperture in the cross piece 12 whereby the gate structure will be held in swinging relation to the remaining mechanism.

In order to eiiiciently support a secondary keyed to the shaft 20. At its other end the shaft 23 is bent to form an arm 27 that eX- `tends at substantially right angles to the general extent of the shaft. A longitudinally slotted yoke 28 is also carried by the cross piece 12, the slots 29 thereof receiving, and serving as guide means for a pair of operating rods 30 and 81, the latter having their inner ends connected and formed into an upstanding projection 32 of the operating rods. However in the drawings I have shown a fastening member 33 for that purpose. It will also be noted that the free ends of the operating rods are bent so as to form hand gripping portions 34.

Passing hence, more to the construction of the gate, it will be noted that the end piece 17 carries a rigid latch bar 35, which, when the gate is in a closed position is disposed in close proximity to a plate 36 carried upon the post 11. In order to form means for retaining the gate in a closed p0- sition, a pair of suitably curved latch members 37 and 38 are pivotally mounted upon the plate 36 as at 39. In order to normally reta-in the latch members in an advantageous position, relative to the latch bar of the gate, the lower ends of the same have connection as at et() with a retractile spring41. The springtl is of course mounted upon the post 11 such as shown at 42. The lower ends of the latch members 37 and 38 also have connection with -iieXible members 13 which in turn have their upper ends connected as at ill to a single liexible elementy L15. The flexible elementfl extends upwardly with respect to the post 11 and is passed through an eyelet 4G which` is. arranged thereon and formed of a length whereby its upper end may be connected to the upstanding projection of theoperating rods. This structure is clearly shown in F ig. 1.

Now in the operation of my improved gate, assuming that the parts are in the position shown in Fig. 1, the operator applies a suitable pressure to either-'of the operating Vrods 30 or 31, either a pulling or pushing pressure, whichever isl most convenient, whereby the flexible `element will be drawn in such a manner as to rock the latch members 37 and 3S into a position whereby free movement of the latch bar is permitted. Simultaneous with thisoperation the a-rm 27 is rocked so as to cause the rotation of the shaft '23 which will of course move the shaft :20 so as to cause the opening of the gate.

From the foregoing it is believed that the advantages and novel features of my inven tion will bel readily understood and therefore further detailed description is deemed unnecessary.

In reducing my invention to practice I lind that the form referred to herein as the most practical and preferred embodiment is the most eflicient, but realizing that certain conditions will necessarily vary in coneurrence with the adoption of my device, I

Copies of this patent mayl be desire to emphasize the fact that various minor changes in the details -of construction and-intheproportion-of parts may be resorted to when required without sacrificing any of the advantages of my invention as defined in the appended claim. c g

Ilaving thus fully described my -:invention,- what Il claim as new and desire to secure by Letters Patent is: Y

In a device of the character described, upstanding supporting'posts, means connecting said postsadjacent theirupper ends, asshaft carried yby one of lsaid'posts andjournaled through said connecting means, extending'longitudinally with'respect to said posts, a gate bodily movable with Vsaid shaft and operating in a path between said posts, a secondary shaft mounted on said connecting means, a beveled: .gearconnection between said shafts, a slottedfguide member onsaid connectinganeans, operating rods extending through said guidegmeans, the inner ends of saidoperatingrods being bent to form anl said shaft upstanding portion, a crank yat one end ofl said secondary shaftpmeansl connecting the crank portionfof said secondary shaft and said.operatingiroda whereby a forwarder i rearward thrust ofsaid operating rods will cause rotation lof=said secondaryV shaft, latch means .carried by one ofsaid supporting posts, :means f connecting "said, latch means i and said upstanding portion. of. said Y operating` rod, and means on saidgate to engage .said latch,meanswhen'said gate is in aclosed position whereby 'upon moving' said operatingrods -said gate may `befopened or -closed andsaid latch meansoperated Vsimul- V taneously.
